“…It is hoped that the latest imaging techniques (computed tomography (CT) and ultrasonography) will prove helpful. However, the interpretation of CT and ultrasonography findings in bladder cancer remains controversial and accurate discrimination does not seem possible by these means (Jaeger et al, 1986;Sager et al, 1983Sager et al, ,1988. Furthermore, neither CT nor ultrasonography is available at all institutions which treat bladder cancer patients.…”

Between 1976 and 1985, 132 patients with T2/T3/T4a bladder cancer underwent cystectomy after pre-operative radiotherapy (46 Gy: 67 patients; 20 Gy: 65 patients). After a median time of 41 months, 62 patients were alive; 51 had died from recurrent bladder cancer and 19 from intercurrent disease without recurrence of their malignancy. Distant metastases developed in 40 patients, accompanied in 5 cases by local recurrence. Local recurrence was the first sign of relapse in 11 patients. In 3 patients the localisation of the relapse remained unknown. The corrected 5-year survival rate was 60%. T category and a palpable bladder tumour were independent pre-treatment prognostic factors in a Cox regression analysis, together with the interval between initial diagnosis and cystectomy. The presence of a palpable tumour before the start of treatment was associated with a particularly poor prognosis in T3/T4a tumours, whereas the survival of patients with non-palpable T3/T4a tumours was similar to that of patients with T2 bladder cancer. Another important prognostic factor was post-irradiation stage reduction (no residual muscle infiltration in the cystectomy specimen). Significantly more patients with non-palpable bladder tumours experienced post-radiation stage reduction than did those with a palpable tumour. However, the prognostic value of stage reduction was statistically significant only in patients with palpable bladder tumours.

“…Other errors of over-and under-staging are due to small tumour size and the presence of scar tissue. If the tumour is larger than 3 cm, a tendency towards overstaging is likely (Jaeger et al, 1986). According to Denkhaus et al (1985), this is due to the loss of penetration and the short focusing of the transducer used.…”

“…Several diagnostic met hods are available to determine how deep a bladder tumour has infiltrated, but most of them fail to predict correctly the final pathological staging. Using clinical examination, including bimanual (transrectal or vaginal) palpation, IVU and urethrocystoscopy, staging errors can be present in more than 40% of cases (Prout, 1982) and in a review by Jaeger et al (1986) range from 0 to 79%. If bimanual examination is performed under anaesthesia, slightly better results can be obtained (Engelmann et al, 1984).…”

Correct staging of bladder tumours is essential for planning the best therapeutic strategy and is therefore directly related to the prognosis. In this study of 15 patients with bladder cancer, a new method using magnetic resonance imaging (MRI) with a newly developed double-surface coil was tested for bladder cancer staging and compared with other existing techniques. Ultrasonography produced 2 cases of overstaging and 2 of understaging. This was due to the inability of this method to evaluate muscular infiltration accurately. All superficial bladder tumours were staged correctly with ultrasound with the exception of 1 case that was overstaged because of superficial tumour calcification. Double-surface coil MRI correctly staged all infiltrating tumours. Two small superficial tumours were missed by MRI, while another superficial tumour was overstaged. It is suggested that double-surface coil MRI and intravesical ultrasonography are good complementary examinations in the pre-operative staging of bladder tumours. Larger studies are necessary to prove the reliability of this conclusion.

“…The transurethral examination yields a high sensitivity concerning muscular infiltration of bladder tumors ( fig. 21,22) [10,14,25]. However, in large tu mors the bladder wall cannot be seen due to the reduced penetration of the high-frequency ultrasound waves ( fig.…”

Transabdominal (suprapubic) sonography of the bladder and prostate is not limited to special indications but should be considered an integrated part of the urologie sonographic evaluation of the genitourinary tract. Information about many pathological conditions (e.g. residual urine, stone, tumor, diverticulum, enlarged prostate) is obtained without delay, without need of instrumentation or exposure to X-rays. Transurethral sonography has proven useful in the differentiation of superficial bladder tumors from deep infiltrating ones. Transvaginal or transrectal examination of the bladder neck has developed into a new modality for urodynamic examination. More than any other diagnostic modality, transrectal ultrasound of the prostate has become a valuable tool for the more correct detection and staging of prostatic carcinoma.
